Abstract
A cable gland assembly includes a hub body defining an internal passage. The cable gland assembly further includes an intermediate body defining an internal passage, wherein the hub body receives the intermediate body, the intermediate body having a first end and a second end opposite the first end, wherein the second end of the intermediate body includes a threaded engagement portion. A gland nut having a first end and an opposite second end, the first end of the gland nut snap-fits to the threaded engagement portion of the intermediate body to secure a cable in the cable gland. A union nut having a first end and a second end, the first end of the union nut is threadedly coupled to the second end of the hub body, the second end of the union nut having a shoulder.
Claims20
A cable gland assembly comprising:
- a hub body having a first end configured to threadedly couple to a structure and a second end opposite the first end, wherein an exterior portion of the second end of the hub body is threaded, the hub body defining an internal passage;
- an intermediate body with an integrated compound chamber defining an internal passage, wherein the hub body receives the intermediate body, the intermediate body having a first end and a second end opposite the first end, wherein the second end of the intermediate body includes a threaded engagement portion that extends outward past the second end of the hub body;
- a gland nut having a first end and an opposite second end, the first end of the gland nut snap-fits to the threaded engagement portion of the intermediate body to secure a cable in the cable gland, the gland nut defining an internal passage such that the internal passage of the gland nut is in fluid communication with the internal passage of the intermediate body;
- and
- a union nut having a first end and a second end opposite the first end, the first end of the union nut is threadedly coupled to the second end of the hub body, the second end of the union nut having a shoulder, the union nut defining an internal passage such that the internal passage of the union nut is in fluid communication with the internal passage of the gland nut and the internal passage of the intermediate body, wherein the gland nut fits within the internal passage of the union nut.

The cable gland assembly of claim 13, wherein the flamepath allows hot gas to dissipate out of the structure.
The cable gland assembly of claim 14, wherein the flamepath allows the hot gas to cool as it travels along the flamepath.
A cable gland assembly comprising:
- a hub body configured to receive at least a portion of a cable;
- an intermediate body configured to receive at least a portion of the cable, the intermediate body having a first portion of the intermediate body that is disposed within the hub body and a second portion of the intermediate body that extends outside of the hub body, the second portion having a threaded external wall;
- a gland nut configured to receive at least a portion of the cable, the gland nut having a first end and a second end, the first end having a plurality of elongated openings extending axially from the first end of the gland nut, wherein the openings define a plurality of circumferentially spaced fingers, the fingers having threaded internal walls that engage the threaded external wall of the second portion of the intermediate body, and the second end having a shoulder;
- and
- a union nut configured to receive at least a portion of the cable, the union nut having a first end and a second end, the first end receives the gland nut and threadedly couples the union nut to the hub body, the second end having a shoulder, the union nut shoulder applies an axial force to the gland nut as the union nut is torqued onto the hub body, wherein the axial force pushes the gland nut toward the intermediate body such that the gland nut engages the threaded external wall of the second portion of the intermediate body.

A method of installing a cable gland assembly comprising:
- providing the cable gland assembly including:
- a hub body having a first end configured to threadedly couple to a structure and a second end opposite the first end, wherein an exterior portion of the second end of the hub body is threaded, the hub body defining an internal passage;
- an intermediate body defining an internal passage, wherein the hub body receives the intermediate body, the intermediate body having a first end and a second end opposite the first end, wherein the second end of the intermediate body includes a threaded engagement portion that extends outward past the second end of the hub body;
- a gland nut having a first end and an opposite second end, the first end of the gland nut snap-fits to the threaded engagement portion of the intermediate body to secure a cable in the cable gland, the gland nut defining an internal passage such that the internal passage of the gland nut is in fluid communication with the internal passage of the intermediate body;
- and
- a union nut having a first end and a second end opposite the first end, the first end of the union nut is threadedly coupled to the second end of the hub body, the second end of the union nut having a shoulder, the union nut defining an internal passage such that the internal passage of the union nut is in fluid communication with the internal passage of the gland nut and the internal passage of the intermediate body, wherein the gland nut is configured to fit within the internal passage of the union nut;
- passing the cable through the internal passages of the hub body, intermediate body, gland nut, and union nut;
- coupling the hub body to the structure;
- inserting the intermediate body in the internal passage of the hub body;
- inserting the gland nut in the internal passage of the union nut such that the gland nut shoulder abuts the union nut shoulder;
- torquing the union nut to threadedly couple the union nut to the hub body, thereby pushing the gland nut to snap-fit to the threads of the engagement portion of the intermediate body to secure the cable in the cable gland;
- untorquing the union nut from the hub body;
- removing the snap-fit engaged intermediate body and gland nut from the hub body, wherein the cable is secured within the intermediate body and the gland nut without the union nut;
- applying a sealant in the internal passage of the intermediate body at the first end of the intermediate body;
- allowing the sealant to cure;
- reinserting the snap-fit engaged intermediate body and gland nut into the internal passage of the hub body;
- and
- torquing the union nut to threadedly couple the union nut to the hub body to secure the snap-fit engaged intermediate body and gland nut in the internal passage of the hub body.
